Bea has $550 more money than Alessandro after 12 months.

Explanation:

So let start with writing the equation for Alessandro money. So we know that the current amount in his/her bank account has $2,400 and she saves $250 per month. So the equation that best fit these terms is:

#y = 250x + 2,400#

Bea has $1,750 in his/her bank account and saves $350 per month. So the equation that best fit these terms is:

#y = 350x + 1, 750#

So for x for both of these equations is 12. So let plug the number in

Alessandro:

#y = 250(12) + 2,400#
#y = 3000 + 2400#
#y = $5400# after 12 months

Bea:

#y = 350(12) + 1750#
#y = 4200 + 1750#
#y = $5950# after 12 months

So subtracting $5950 and 5400 gives us a $550 difference.
